SNOWPLOW.

Application led March 10,1925. Serial No. 14,458.

To all wiz-om t may concern:

Be it known that I, JOHN BARRY, a citizen of the United States, residing at Marcus, in the county of Cherokee and State of Iowa, have invented a certain new and useful Snowplow, of which the following is a specification.

The object of my invention is to provide an efficient snow plow of comparatively simple, durable and inexpensive construction.

A further object is to provide such a structure adapted to be conveniently and quickly attached toa Fordson tractor or other tractors or trucks, and having an auger at the front for plowing and disposing of the snow.

Still a further object is to provide such a structure having a blower for blowing the snow to the side of the road, and means for operating the auger and blower from the en ine of the tractor.

till a further object is to provide a means for adjusting the plow relative to the road surface, or raising it to inoperative position.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various elements of my snow plow, whereby the objects contemplated are attained, as hereinafter set forth, 'pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of my improved snow plow, shown attached to a Fordson tractor.

Figure 2 is a side elevation of the same, parts f the blower casing being broken away to better illustrate the details thereof.

Figure 3 is a sectional view on the lines 3-3 of Figure 1.

Figure 4 is a sectional view on the lines 4-4 of Figure 1; and

Figure 5 is a front elevation of the upper portion of the radiator, showing part of my hoisting mechanism attached thereto.

In the accompanying drawings, I have used the-reference numeral to indicate generally a Fordson tractor. The radiator -is indicated by the numeral 11. A frame consisting of uprights 12, attaching members 13 and a supporting member 14, has pulleys 15 rotatably mounted at its upper end. The attaching members 13 are secured to and extend forward from the uprights 12, and are attached to the shell of the radiator 11 by cap screws 16.

A U-shaped frame member 17 is pivotally mounted to the rear axle housings 18 by means of U bolts 19 passing therearound. A frame member 20 is attached to the forward end of the U frame 17 and supports the snow handling mechanism.

A frame member 21 is attached to the U frame 17 and provides a bearing support for the shafts of the raising and adjusting mechanism, which will now be described.

A hand wheel 22 is fixed to a shaft together with a worm 23. The worm 23 is in mesh with a worm gear 24, which is fixed on a shaft together with a winding drum 25.

A pair of cables 26 are attached to the drum 25. One of the pair of'cables 26 extends over one of the pulleys 15 and then down to the frame 20, to which it is attached. The other cable 26 extends around pulleys 27, over the other pulley 15 and then down to the frame 2() to which it is attached.

From the foregoing, it will be' seen that by manually operating the hand wheel 22, the drum 25 will be rota-ted, causing the cables 26 to be either extended or retracted, thereby lowering or raising the frame 20 which carries the snow handling mechanism. B referring to Figure 2, it will be noted that the axle 18, pulley 47 and shaft 50 are nearly-in line. This allows suficientpivotal movement of the frame 2O to adjust the auger 28 relative to the road surface being traveled over without materially tightening or loosening the belt 48. When it is desirable to raise the auger 28 high, as for traveling from'one place to another, the belt 48 may be removed.

The snow handling mechanismcomprises an auger 28, and a blower 29. Back of the auger 28 is a blade 30 curved to conform to the periphery ofthe auger. This blade 30 provides a back for the snow to come against which is then conveyed laterally by the rotation 'of the auger 28.

A hood 31 is mounted on spokes 32, which terminate in a bearing and are pivoted on the auger shaft 33.

Rods 34, having heads 34, are hinged to the hood 31, and pass freely through brackets 35 on the frame 20.

A spring 36 on each rod 34 holds the hood 31 inthe position shown in Figure 3.

lVhen the snow overloads the auger 28, the hood 31 will swing backward against the action of the springs 36. This causes the front end of the hood 31 to rise and prevent los the snow from rolling over the auger, and be left behind. The rising hood also warns the driver that he is crowding his machine.

Teeth 37 are formed along the periphery of the auger 28, and serve to cut up the snow and thus facilitate handling it.

My machine may also be used in the summer as a road scraper in which case these teeth crumble the bumps on the road over which the machine is travelling and leave the road in a smooth condition.

The snow is conveyed laterally along' the blade 30, then up a chute 38, and into the blower 29. The blower blades 39 cause the snow to be expelled through a conductor pipe 40 by centrifugal force.

A hood 4l deflects the snow downwardly to the ground.

The conductor pipe 40 is rotatably mounted on the blower 29.

For rotating the conductor pipe 40, and thereby depositing the snow at any desired distance from the tractor, I have provided the following described mechanism.

A worm gear 42 is attached to the outside of the conductor pipe 40. Mounted in suitable bearings 43 is a shaft 44 having a worm 45 secured thereto and a mesh with the worm gear 42. By rotating the crank 46, the conductor tube 40 may be swung to any desired position.

The auger 28 and the blower 29 are operatively connected to the engine of the tractor through the following described mechanism.

The Fordson tractor is provided with a drive pulley 47, which is operatively connected with the fly wheel of the engine by an internal gearing arrangement, not shown, as it is in the usual Fordson construction.

A belt 48 transmits power from the drive pulley 47 to a pulley 49 mounted on a shaft 50 in bearings 51. The bearings 51 are attached to the frame 20.

A sprocket 52 is attached to the outer end of the shaft 50.

A sprocket 53 is attached to the shaft of the blower 29, and a sprocket 54 is attached to the auger shaft 33.

A chain 55 is trained around the above described sprockets in the manner shown in Figure 2.

From the foregoing it will be seen that I have developed a simple, yet satisfactory means for imparting rotation to my auger and blower from the drive pulley of the tractor.

For plowing, a wider path, I have provided an extension auger A, being of similar construction to the auger already described. I will refer to like parts by like reference numerals with the addition of the character a.

The shaft 33a of the auger 288L is journaled in bearings 56 on a frame 20a, and is connected b v a universal joint 57 to the auger shaft 33. The frame .2()a is pivoted at 58 to the frame 20.

For raising the extension auger A, I have provided a winding drum 59 having a cable 6() attached thereto, and secured to the frame 2()a at 6l.

A worm gear 62, attached to the drum 59, is in mesh with a worm 63 on a shaft 64.

From the foregoing, it will be seen that by rotating the crank 65, the extension auger A may be adjusted relative to the mam auger 28.

It is to be understood that suitable braces 66 may be used wherever needed without their description beingl necessary.

It is to be understood that the driving means has the proper proportions for rotating the angers at the best working speed and that these proportions may be changed as determined by experiment. My snow plow can also, by slight changes in the attaching means, be used in connection with tractors other than the Fordson or with trucks.

Some changes may be made in the construction and arrangement of the various parts of my invention, without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:
